Specifies the physical unit type. The physical unit type depends on the type of cluster controller (such as 3767, 3174, or AS/400®). To determine the physical unit type for a given device, see the component description manual for that device.
For a type 2.1 physical unit, code PUTYPE=2.
For switched subarea connections, code PUTYPE=4 or PUTYPE=5. PUTYPE=4 defines the physical unit as an NCP. PUTYPE=5 defines the physical unit as a VTAM®.
Note: For PU types 4 and 5, an auto call unit (ACU) is required
for subarea dial connections to be established.
The physical unit type for a LAN switched station must be 2.
For a PU type 1 or 2, or type 2.1, the value of PUTYPE occupies bits 4–7 of the 48-bit station ID constructed by VTAM for switched network operation. See IDNUM for a description of the station ID.
Note: The only valid value for Enterprise Extender is PUTYPE=2.
